The pull of gravity is just matter sliding along the curvatures of space-time. Einstein shot to the pinnacle of celebrity in 1919, when British astronomers actually measured this warping.
We spoke with theoretical physicist Brian Greene about Einstein's theory of space-time. Many scientists believe space-time is a fundamental concept. But Greene thinks there might be something ...
A rare Einstein ring spotted near our galaxy offers a unique chance to test Einstein’s general relativity and study the ...

Space-time may hide a bizarre new kind of black hole that causes Einstein’s theory of gravity to fail – and could solve the ...
A weak gravitational field indicates nearly flat space-time, and there Newton's theories seem to apply. But a strong gravitational field throws classical predictions off. Einstein postulated three ...
The structure is nearly 600 million light-years from Earth and is an early display of the nascent dark matter telescope's ...
